3 Claims.

My invention relates to a parenteral administration unit, so constructedas to permit emergency injections through said unit.

When a seriously injured or sick person is given a parenteraladministration the person sometimes begins to sink and it is necessaryto administer adrenalin or other restoratives' or stimulants. The veinsof a sick person are often difli cult to find and loss of time mightresult in death.

The object of this invention is to provide a construction whereby theneedle containing the adrenalin or the like may be inserted into theparenteral administration apparatus so that the restorative or stimulantmay pass through the parenteral administration needle into the per.-sons vein and blood stream without removalof the parenteraladministration needle, or interruption of the parenteral administration.This saves locating another vein in the person and eliminates theinsertion in the person of a second needle. Time is saved andsatisfactory administration is assured. Sometimes death may beprevented.

My invention also contemplates such other objects, advantages andcapabilities as will later more fully appear and which are inherentlypossessed by my invention.

While I have shown in the accompanying drawing a preferred form of myinvention, yet I wish it understood that the same is susceptible ofmodification and change without departing from the spirit of myinvention.

Referring to the drawing, Fig. 1 is an elevational view of my parenteraladministration unit; Fig. 2 is a detailed elevational view of myadapter; Fig. 3 is an elevational view of the insertion of the secondneedle into the adapter for use, and Fig. 4 is an enlarged sectionalview of the adapter, sealing member and the connection with the tubing.

The embodiment selected to illustrate my invention includes a container10 containing desired solution. For the administration of the solutionthe container I is inverted with bale H held by standard l2. Within neck13 is a suitable plug [4 having air opening I5 receiving one end ofhollow air tube It which extends into the container 16. Another openingI! in plug l4 receives connector l8 to which is attached tubing l9.

Into 'the other end of tubing I 9 is inserted an adapter 20. Saidadapter 20 has a rear shank ortion 2!, and a slightly reducedintermediate portion 22 with a shoulder 23 therebetween. Adjoining theintermediate portion 22 is an enlarged portion 24 having spacedshoulders 25 and 26. Beyond said enlarged portion 24 is a reducedforward portion 21 having a slight inward taper. Said forward portion 21is adapted to receive the rounded inner end portion 28 of a needle 29and to hold the same in position by friction grip.

The tubing I9 preferably extends forwardly to shoulder 25 of enlargedportion 24, and is positioned over a portion of transparent ortranslucent rubber sealing member 30. Member 30 contacts adapter 20,extending forwardly beyond shoulder 26 and rearwardly beyond rear shankportion 2| as shown in Fig. 4. An outer rubber cover or band member 55is tightly positioned over that portion of tubing 19 between shoulder 25and rear shank portion 2|.

My adapter 20 has a central bore 3| extending therethrough. An opening32 is provided in enlarged portion. 24 communicating with bore 3|. Iprefer that the opening 32 extend diagonally forwardly to bore 3l so asto receive all of the beveled portion of an inserted needle. Thisprovides better. communication and faster passage of liquid as well aspreventing any liquid from being lost.

In use, let us assume that a person receiving a parenteraladministration suddenly begins to sink. Adrenalin or the like must beinjected immediately to save the persons life. There is no time to findanother vein to insert another needle. There is no time to withdraw theparenteral administration needle and insert the adrenalin needle. Theuser, being able to see opening 32 through transparent member 30, merelypierces sealing member 30 with the needle 33 of a syringe 34 filled withadrenalin or the like, presses needle 33 into opening 32 and actuatesthe plunger 35. The adrenalin flows through opening 32 into bore 3! andout needle 29 into the persons blood stream. The needle 33 is thenwithdrawn and the opening in sealing member 30 closes. The parenteraladministration, which has not been interrupted, continues.

Having thus described my invention, I claim:

1. A parenteral administration unit comprising a container havingsterile injection solution therein, a plug normally sealing the neck ofsaid container, said plug having air inlet means and liquid outlet meansadapted to function when said container is being used, a tubingconnected on one end to said liquidoutlet means, an adapter having arear shank portion attached to the other end of said tubing, saidadapter having a tapering front portion and an enlarged portion havingspaced shoulders between said rear and front portions, said adapterhaving a bore extending therethrough, said enlarged portion having anopening extending diagonally forwardly to communicate with said bore, atransparent sealing member positioned on said adapter and covering saidopening in said enlarged portion, an injection needle attached to saidtapering front portion, said injection needle adapted to be injectedinto the vein of a person designed to receive the injection solution insaid container, a second needle in communication with a source ofemergency stimulating solution said sealing member adapted to be piercedby said second needle, and said opening in said enlarged portion adaptedto receive said second needle and emergency stimulating solution fromsaid second needle for communication to said bore, thence to saidinjection needle and into the vein of the person receiving the injectionsolution from said container, without removing said injection needlefrom the person and without inserting said second needle into theperson.

2. A parenteral administration unit comprising a container havingsterile injection solution therein, a plug normally sealing the neck ofsaid container, said plug having air inlet means and liquid outlet meansadapted to function when said container is being used, a tubingconnected on one end to said liquid outlet means, an adapter having arear shank portion attached to the other end of said tubing, saidadapter having a tapering front portion and an enlarged portion betweensaid rear and front portions, said adapter having a bore extendingtherethrough, said enlarged portion having an opening extending tocommunicate with said bore, a transparent sealing member positioned onsaid adapter and covering said opening in said enlarged portion, aninjection needle attached to said tapering front portion, said injectionneedle adapted to be injected into the vein of a person designed toreceive the injection solution in said container, a second needle incommunication with a source of emergency stimulating solution, saidsealing member adapted to be pierced by said second needle, and saidopening in said enlarged portion adapted to receive said second needleand emergency stimulating solution from said second needle forcommunication to said bore, thence to said injection needle and into thevein of the person receiving the injection solution from said container,without removing said injection needle from the person and withoutinserting said second needle into the person.

3. A parenteral administration unit comprising a container havingsterile injection solution therein, a tubing connected on one end tosaid container, said container having means to permit the flow of theinjection solution to said tubing, an adapter attached on one end tosaid tubing, an injection needle attached to the other end of saidadapter, said injection needle adapted to be injected into the vein of aperson designed to receive the injection solution in said container,said adapter having a bore extending therethrough to providecommunication between said tubing and said injection needle, saidadapter having an opening in its side wall extending therein forcommunication with said bore, a transparent sealing member positioned onsaid adapter and covering the opening in the side wall of said adapter,a second needle in communication with a source of emergency stimulatingsolution, said sealing member adapted to be pierced by said secondneedle and said opening adapted to receive said second needle andemergency stimulating solution from said second needle for communicationto said bore, thence to said injection needle and into the vein of theperson receiving the injection solution from said container, withoutremoving said injection needle from the person and without insertingsaid second needle into the person.
